24038Spherical Roller Bearings

24038 Spherical Roller Bearing | 24038CA / 24038CC / 24038K Cage And Application

The 24038 is a large-size double-row spherical roller bearing with standard dimensions of 190×290×100mm. Designed with a wide cross-section and robust internal structure, it delivers powerful radial and axial load capacity, reliable self-aligning tolerance and stable low-friction operation. The bearing effectively compensates shaft misalignment, absorbs persistent mechanical vibration, and withstands long-term low-speed, heavy-torque cyclic loads, making it an essential component for heavy industrial machinery. The 24038 series features three mainstream models: 24038CA, 24038CC and 24038K, each with unique cage and bore designs to suit different working environments and budget demands.

24038CA Bearing (Solid Brass Cage)

24038CA utilizes a one-piece machined solid brass cage paired with a symmetrical ribless roller structure. The high-rigidity brass cage offers superior high-temperature resistance, impact stability and fatigue resistance during continuous high-load operation. It minimizes internal friction, heat buildup and operational noise while maintaining precise roller guidance and consistent rotational stability. Resistant to structural deformation under shock loads and harsh thermal conditions, this model ensures extended service life and ultra-high operational reliability. It is the ideal choice for critical industrial equipment that requires non-stop, failure-free performance in demanding working conditions.

24038CC Bearing (Stamped Steel Cage)

24038CC comes with a two-piece stamped steel cage and floating guide structure. The lightweight steel construction optimizes internal bearing space, allowing larger roller contact areas and improved overall load-bearing efficiency. Featuring low friction, excellent wear resistance and stable medium-speed performance, this model adopts fully standardized manufacturing for high versatility and exceptional cost performance. It runs smoothly under regular heavy-cycle loads and daily mechanical vibration, providing consistent long-term stability. As the most economical universal version in the series, it is widely used for standard heavy-duty industrial machinery.

24038K Bearing (Tapered Bore)

24038K is equipped with a 1:12 tapered bore for flexible installation and adjustable internal clearance. Compatible with adapter and withdrawal sleeves, it enables quick assembly, disassembly and accurate gap calibration during maintenance. The tapered bore design effectively offsets shaft deflection and assembly errors, significantly improving the overall stability of heavy-load transmission systems. Retaining all self-aligning and high-load advantages of standard spherical roller bearings, this model simplifies routine upkeep and shaft alignment, perfect for equipment requiring regular inspection and clearance tuning.

Industrial Applications

24038 series bearings serve a wide range of heavy industrial applications. 24038CA is preferred for high-temperature and high-impact equipment including metallurgical mills, heavy-duty gear reducers and large mining machinery. 24038CC is ideal for general heavy machinery such as construction equipment, vibrating screens, chemical processing machines and paper-making units. 24038K is commonly installed on large industrial fans, heavy conveyor systems and general transmission equipment needing flexible installation and easy maintenance.

Product Summary: 24038CA delivers maximum durability for harsh environments, 24038CC provides reliable cost-effective universal performance, and 24038K offers adjustable assembly solutions, fully covering low to medium-speed heavy-duty industrial operation scenarios.
